Chronos-2 reads up to the last 512 values of a series and says what probably comes next: a middle line, and a band where 8 in 10 outcomes should land (the 10th to 90th percentile).
I once hand-built a stock trend predictor out of moving averages and linear regression, tuned for that one stock. This model needs no training on your data at all; it has learned what series in general tend to do.
